بیشترMechanical Properties. CF8M and CF8 stainless steels also have different mechanical properties. CF8M has a higher yield strength and tensile strength than CF8, meaning it is better suited for applications that require high strength. However, CF8 has better ductility than CF8M, which is more resistant to cracking during welding.
بیشترNote 1: This specification covers the low-temperature requirements particularly pertinent for ferritic and martensitic steels. Certain grades of austenitic steel castings furnished in accordance with Specification A351/A351M have been found suitable for low-temperature service down to −300 °F [−184 °C] and others down to −425 °F …
